.The table 7 has the end bearings 22 and the central bearing 23-. Theend bearings 22 form the support for the hollow spindle 24, said spindlehaving the flanged end portion '25.. Within the spindle 24 is theroll-arbor 26 which carries at its outer end the roll 27.

This sleeve 34 takesthe thrust of the spindle 24 due to the rollingoperation andball thrust-bearings 37'are prbvided between the flangedportion 88 of the Spindle 24 and the end of the sleeve 34 ,which isbacked up by the lock-nuts 34*. By this construction the horizontaladjustment of the spindle 24 may be efiected by slackening one of thering-nuts 35 and tightening up the other.

The upper roll 39 is mounted in the same manner as the lower roll 27 andthe samereference numerals have been used to indicate the same parts asdescribed in connection with the lower roll 27. In Fig. 4, however, thekey 30 is shown in detail, said key being interposed between the innerend of thearbor 2'6 and the spindle 24*s0 that by ease of thelower-roll, a universal spindle'40.

with spherical ends 4i is interposedbetween the spindle "and the driv nrshaft ,42. This provides the 'nee'essfijlfy, fieiiihili'ty, when thetable 7 I aying the realis raised i to working peg-man,- as indicated indotted lines,

the annular blank or disk to be rolled is placed on the roll-portion39,-and the lower roll is then raised by admitting motive fluid to thecylinder 5, whereby the ram is raised and the table '7 supported therebyis moved upwardly. the parallelism of said tablebeing maintained bymeans of the bell-cranks 8 and the other connections hereinbeforede.scribed, so that said table moves without undue strain or wearing on theparts, and more especially the wear pieces 17 and 20 at the cornersthereof. The table is raised until the roll portion 1.7 comes intocontact with the blank. Both rolls are then caused to revolve and thepressure which is brought to bear by the ram 6 on the blank causes thelatter toexpand diametrically as its thickness is reduced, but the widthcannot increase beyond the amount determined by the dis tan'ce betweenthe flanges 25 of the spindles which overlap therolls, as indicated inFig. 4. By having the cylinder 6 arranged in the position indicated, thepressureapplied by the ram and through the roll-portion 27 to the tireblank is such that the center of load is'i'n line with the centerof'pressure. This in connection with the parallelism maintained by thetable in its movement reliev'e's the guides of excessive loads whichincreases the efliciency of the machine and reduces the wear and teat. I

By my invention, I provide for the adjustm'ent of the rollslongitudinally, as well as the spindles, to provide against wear thattakes place in-the disks or flanges 25 and to ,vi'dedwith theindependent adjustment by means of the cotters 29 and, the keys 30.v Bymy invention vwith the useof one set of spindles rolls with workingportionsof different sizes may be inserted in said spindles,-

and so reduce the cost of operation.
